They did so for the Olympics by stopping a lot of polluters from operating.

As soon as the games left town, the pollution came back.

beijing's air quality did not get worse after the olympics. (edited to clarify)

I decided just to google Beijing air quality and both results came back... Not so good.

"Dangerous Any exposure to the air, even for a few minutes, can lead to serious health effects on everybody. Avoid outdoor activities." https://www.accuweather.com/en/cn/beijing/101924/air-quality...

"Very Unhealthy Health warnings of emergency conditions. The entire population is more likely to be affected." https://aqicn.org/city/beijing/

So not sure I fully believe that.

true, but it wasn't any better during the olympics and i think it was much worse before that. i only got there shortly before the olympics so all i can confirm is that it did not get any worse after.

according to this report air quality in beijing continuously improved for the last few decades:

There is more to China than just Beijing.

yes, but the olympics were mainly in beijing, so when it comes to the question of what happened with the air quality after the olympics, beijing matters the most.
